Fix MISRA rule 10.1 violations involving gk20a_nonstall_ops
enums by replacing them with with corresponding #defines.
Because these values can be used in expressions that require
unsigned values (e.g. bitwise OR) we cannot use enums.
The g->ce2.isr_nonstall() function was previously returning an
int that was a combination of gk20a_nonstall_ops enum bits which
led to the violations.

In the current code, gk20a.h includes io.h which gets directly included
in a lot of other files. io.h contains methods which uses a struct
gk20a as a parameter leading to a circular dependency between io.h
and gk20a.h. This can be mitigated by removing io.h from gk20a.h as
part of larger effort to moving gk20a.h to nvgpu/gk20a.h

Switch all logging to nvgpu_log*(). gk20a_dbg* macros are
intentionally left there because of use from other repositories.
Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages
are deleted.

Replace the padding in nvgpu_channel_wdt_args with a timeout value in
milliseconds, and add NVGPU_IOCTL_CHANNEL_WDT_FLAG_SET_TIMEOUT to
signify the existence of this new field. When the new flag is included
in the value of wdt_status, the field is used to set a per-channel
timeout to override the per-GPU default.
Add NVGPU_IOCTL_CHANNEL_WDT_FLAG_DISABLE_DUMP to disable the long debug
dump when a timed out channel gets recovered by the watchdog. Printing
the dump to serial console takes easily several seconds. (Note that
there is NVGPU_TIMEOUT_FLAG_DISABLE_DUMP about ctxsw timeout separately
for NVGPU_IOCTL_CHANNEL_SET_TIMEOUT_EX as well.)
The behaviour of NVGPU_IOCTL_CHANNEL_WDT is changed so that either
NVGPU_IOCTL_CHANNEL_ENABLE_WDT or NVGPU_IOCTL_CHANNEL_DISABLE_WDT has to
be set. The old behaviour was that other values were silently ignored.
The usage of the global default debugfs-controlled ch_wdt_timeout_ms is
changed so that its value takes effect only for newly opened channels
instead of in realtime. Also, zero value no longer means that the
watchdog is disabled; there is a separate flag for that after all.
gk20a_fifo_recover_tsg used to ignore the value of "verbose" when no
engines were found. Correct this.

Some GPUs require all channels to be on TSG and also have larger than 4GB
vidmem sizes which were not supported on the previous CE2 code.
This change creates a new property to track if the copy engine needs to
encapsulate its kernel context on tsg and also modifies the copy engine code
to support much larger copies without dramatically increasing the PB size.

Support only VM pointers and ref-counting for maintaining VMs. This
dramatically reduces the complexity of the APIs, avoids the API
abuse that has existed, and ensures that future VM usage is
consistent with current usage.
Also remove the combined VM free/instance block deletion. Any place
where this was done is now replaced with an explict free of the
instance block and a nvgpu_vm_put().

Since all debugfs code is Linux specific, remove
it from common code and move it to Linux module
Debugfs code is now divided into below
module specific files :
common/linux/debug.c
common/linux/debug_cde.c
common/linux/debug_ce.c
common/linux/debug_fifo.c
common/linux/debug_gr.c
common/linux/debug_mm.c
common/linux/debug_allocator.c
common/linux/debug_kmem.c
common/linux/debug_pmu.c
common/linux/debug_sched.c
Add corresponding header files for above modules too
And compile all of above files only if CONFIG_DEBUG_FS is set
Some more details of the changes made
- Move and rename gk20a/debug_gk20a.c to common/linux/debug.c
- Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h
- Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call
gk20a_init_debug_ops() directly from gm20b_init_hal()
- Update all debug APIs to receive struct gk20a as parameter
instead of receiving struct device pointer
- Update API gk20a_dmabuf_get_state() to receive struct gk20a
pointer instead of struct device
- Include <nvgpu/debug.h> explicitly in all files where debug
operations are used
- Remove "gk20a/platform_gk20a.h" include from HAL files
which no longer need this include
- Add new API gk20a_debug_deinit() to deinitialize debugfs
and call it from gk20a_remove()
- Move API gk20a_debug_dump_all_channel_status_ramfc() to
gk20a/fifo_gk20a.c

Move the platform_gk20a.h include out of the ifdef CONFIG_DEBUG_FS
in the CDE code since dev_from_gk20a() is used regardless of
whether debugfs is enabled.
Also modify some of the CE ops to take a struct gk20a instead of a
struct device. This avoids any requirement for including
linux/device.h or platform_gk20a.h.

This involves adding HAL ops for the fifo HAL functions that get

leaving it only managing channels in software and push buffers.

pbdma_acquire_val consisted both of channel logic and hardware
programming. The channel logic was moved to the caller and only
hardware programming was moved.

This change refactors the teardown in remove to ensure that it is
possible to unload the driver while leaving fds open. This is achieved
by making sure that the SW state is kept alive till all fds are closed
and by checking that subsequent calls to ioctls after the teardown fail.
Normally, this would be achieved ny calls into gk20a_busy(), but in
kickoff we dont call into that to reduce latency, so we need to check
the driver status directly, and also in some of the functions
as we need to make sure the ioctl does not dereference the device or
platform struct
